Once installed, these function very well, look good, and are really sturdy. Obviously cutting the mortise in your door takes a steady hand and a tool appropriate for the job. I cut into pocket doors without dismounting them, which makes the operation a little more difficult. If I recall, these ended up kind of pressure fitting into the mortise and then secured with a couple screws. The floor plate is also best recessed and looks really good when fit well.

Mortised the door to accept them, and they look great. Obvious door modification is required if no existing mortise pockets, but once installed, the door feels strong, the bolts are long enough to not need to raise the threshold, it looks clean and it feels very secure.Respectfully,Nathan Evans

Seems sturdy and was not hard to install. Serves its purpose well. My only complaint is that the lever is hard to pull. I have to pry it up with a tool to open or close.

Easy to install if you have the tools.I was surprised/impressed with the overall design and durability.

Worked great for my patio doors. Make sure you have the length and width correct.

It's very sturdy. I do recommend for you.

Very good quality and made to install easily. Just as good quality that I had used 4 decades ago.

The media could not be loaded. I bought this to keep one of my double doors in place. It did do the job, but 1 of them came off track when I was trying to latch into the frame. The other one worked exactly as expected, after I found the proper placements using the first one. I’m using it for an interior door. Not quite sure if I would use it for an exterior door. Feels pretty sturdy for my interior door.
